Direction of rotation: counterclockwise viewed from power take-off side.
The starter motor is highly compact and reliable and therefore rarely gives any type of problem. In case of malfunction, ensure that the starter motor wiring terminal is properly tightened under the nut and shows no sign of corrosion. If the terminal is properly tightened and free from corrosion, remove the starter motor and test it under no-load conditions (no load applied to the shaft). Secure the starter motor to a test bench, making sure you do not damage the casing. Use a fully charged 12 V battery for the test. Use battery-motor connection cables which are no longer than 70 cm and with the same cross-section as the cable on the motorcycle itself. Connect the negative terminal of the battery to an unpainted area of the starter motor casing and the positive terminal to its electrical terminal. The shaft of the starter motor should rotate freely and at high speed. Take care not to short-circuit the two cables connected to the battery.
